I know by default member server syncs time from domain hira. Now with
hklm\....w32time\parameter\type set to [AllSnyc] and config\ntpserver
set to [a manual list], would the member server still try getting time
from DCs? If yes before or after the manual list?

Curious, any reason you are making registry changes for the time service?
Are you trying to get away from using the domain hierarchy? Time sync is
important due to Kerberos' 5 minute skew allowance. I usually like to
recommend to stay away from configuring the time service in the reg and use
the command line tools.

I have a blog on configuring and troubleshooting the time service. I hope
you find it helpful.

Hello strongline,

Do not manual set another time server in a domain on member servers or DCs
other then the PDCEmulator. It is important that only the PDCEmulator as
domain time master is the source for time and configured to an external time
source.

Hello Jonathan de Boyne Pollard,

You are of course right when saying the kerberos time must be in the correct
time window of default 5 minutes in a domain. But when using different time
sources on the servers you are out of sync more quick then you like it.

That is the the reason that the DC with the PDCEmulator is the time master
in the domain automatically where all other DC sync with and the other domain
machines sync with one available DC. This is the ONLY way to guarantee this.

- When you say:

"It is important that only the PDCEmulator as domain time master is the source for time and configured to an external time source."



Why the PDCe and not other DC?

Time sync is important, true, but the key is to have all (workstations, DCs, member servers in sync) synchronized. The PDCe is the Authoritative time server because by default the PDCe is one of the Roles that the First DC has, additionally that server will also serve as Authoritative Time server, but that doesn't mean that you must stay with that configuration, there're many scenarios were that isn't possible.

Well I suppose you could set it all up yourself but why bother. The DCs use the
PDC, the other PCs use one of the DCs and if you have a multi-domain forest then
the subdomain's DCs get their time from the parent etc. Why bother to set up a
complex alternative especially when you need to consider failure and fallback
configuration.

Ace referenced an article which also has a link to a MS article that explains
how much would need to be done.

First, what you say may apply in your network scenario, but there're many
others that need to change for may different reasons, each environment has
different requirements. One thing that people forget, is that NOT always
things are configured correctly at the first time, and for many different
reasons they need to change them. Setting up a new Authoritative server is
NOT a complex task coordinating those changes, may be, in some environments
a challenge to ensure that no-one "suffers" with those same changes.

Jonathan,

Two questions
Whats the easiest way to sync the time?
What are you doing outside of a OS2 group?? :)

For Active Directory, the easiest way is in the general case is quite
likely going to be to go with what's supplied out of the box. As I
wrote in the messages that you replied to, one manually configures the
machine at the top of the Windows Time Service hierarchy, and everything
else "just works". That's the intention of the design. But as M. Silva
has pointed out, there are going to be many situations where this
doesn't happen, not least because not every domain is set up and
maintained perfectly ab initio. It's not difficult to undermine the
bases upon which "just works" just works, through error and otherwise.
And as has also been pointed out, the Windows Time Service design is
sometimes not what one wants. (One prior thread in MPWSA, for example,
was started by someone who apparently didn't want the three minute
threshold that the WTS implements and who wanted all adjustments to be
incremental. Another prior thread was started by someone who wanted the
opposite, and wanted no incremental adjustments. Knowing the constraints
and design choices of the WTS design is important.)

Sometimes the easiest way, for AD, is not the right way nor the desired
way. In this thread, the point is that it's most certainly not the only
and the mandatory way, as has unfortunately become received wisdom in
some places.

Though I see the discussion here has gone to a slightly different
direction, I thank all who replied. If it was me, I wouldn't have
wanted to change its default behaviour. Now things are as it is, I
need to figure out how Windows decide the order of all available time
sources. I've read all links recommended before I came to this forum.
None of them mentions the exact order, thus my question.

No. Manual lists are (normally, not mandatory) to be used with external
providers, and that applies to the Authoritative time server. For internal
use, you should stay with the defaults that follows the domain hierarchy. If
you plan not to use internal/domain hierarchy, you may run into
authentication issues.

I hope that the information above helps you.
Have a Nice day.

<p>You surprise me.  I was expecting the usual response.  I've done it
for you.  I'm not sure <em>why</em> it's the usual response, mind
you.  Such a response seems like simple amplification of the problem,
to me.  This particular message that you replied to currently has a
Breidbart Index of 9, which is less than the required threshold.<br>

I should have just ignored it, knowing it was spam. And honestly, I never heard of the Breidbart Index, so I had to look it up. :-)
